To all whom "it may concern Be it known that we, EDWIN L. Sour]:-

WICK and REUBEN M. SOUTHWICK, citizens,

of the United States, residing at Malta, in the county of Phillips and State ofMontana, have inventedcertain new. anduseful Improvements in Cutter-Bar Guards; and we do hereby declare the following to be a full,

clear, and exact description of the invention, .7

such as will enable others skilled in the art to which it appertains to make and use the same. 3 I p This invention relates to guards for cutter bar constructions, such as are. used upon mowing machines, harvesters, or like agricultural implements. Y I The primaryobject of this invention is to provide a guard finger as specified,'which is composed of an upper and lower section, which are pivotally connected, adjacent to the point of the finger or guard, and which have heads formed upon their ends remote from their pivotal ends, for facilitating'the connection of the finger guard to a cutterv bar, and further to provide meanswhereby the guard fingers may be 'attached to any cutter bar of ordinary construction.

With the foregoing and other objects in view thisinvention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described,illustrated in the accompanying drawings and claimed 1 In describing; the invention in. detail, reference will be had to they accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a plan view of a fragment of a cutter bar, showing a plurality of improved guard fingers attached thereto, Fig. 2 is a side'elevation of one of the guards, Fig. 3 is a longitudinalsection through one of the guards, Fig. 't isa cross section through one of the finger guards taken on theline 4-45 of Fig. 2, and Fig. 5 is a per- J spective view of the ledger-plate.

Referring more particularly to the draw-. ings, 1 designates a cutter bar. of ordinary construction, to which is attached a pluralityofthe guards or guard fingers, generally designated by the numeral 2;

The guards 2 include a top section 3 and a bottom section 4, which are pivotally connected as is shown at 5. The bottom sec tion 4 has the ordinary type of point 6 formed thereon, and" it is provided with a recess 7 formed in its upper surface and eX- tending downwardly and v longitudinally therein. The topsection 3 has a tongue 8 formed thereon, which is seated in a portion of the opening 7 and, is pivotally connected to the portionof the bottom section twhich forms the sides of the recess of apin 9.

Thetop'section 3 of the guard, has a boss 10 formed upon its end remote from the end which is pivotally connected at 5, which boss;

is provided with a slot 11, which is substantially rectangular shaped, and which alines with a slot 12 formed in the boss 13. The boss 13 is formed upon the ends of the bottom section 4, and is provided. for en- 7, by means.

gagement with the under surface of the cutter bar, while the boss 10 engages the upper surface of the cutter bar, for attaching the guards to the cutter. bar. "The upper surface of the b0ss110 is Corrugated, as is shown at 14, and it is provided for co-action with the corrugated under surface 15 of the bolt headl6. Thebolt head 16 is formed upon a bolt l7, which. is provided with a rectangular portion 18, that extends through the slot 11 for holding the guard fingers against pivotal movemen I I The bottom section 1 of the guard, has an upstanding shoulder 20 formed thereupon, which is provided with a cutout portion 21 formed in theedge of the same which faces the point 6. The cutout portion 21 has its ledger plate 23 has a tongue 24 formed upon the end remote from the'beveled or inclined end 22. The tongue 24is inserted between the sections of the bottom section 41 which forms sides forv the cutout portions 7 as is clearly shown in Fig. 3 of the drawings. To attach the ledger plate 23, the inclined end. 22 is inserted within the cutout portion or recess 21, and the ledger plate is moved to a horizontal position, and the tongue24 within the cutout portion 7, would securely hold the ledger plate attached to the guard.

'The sides of the ledger plate areserrated,

as is shown at 25. The shoulder 20 extends ,beyond the: sides of the body of the guard fingers proper as is shown ,at;27, and 28. The projections27, which extend outwardly from the body of the'gua'rd fingers, are provided with hollow conical portions 29, which are adapted" for receiving the conical portions 30, which are formed upon the outer ends of the projections 28, for properly spacing and uniting the various guards and also alining a plurality of guard fingers when attached to a cutter bar, as is clearly shown in Fig. 1 of the drawings.

The top section 3 has a plate 31 secured to the under surface of the same, which is adapted to rest upon the upper surface of a sickle bar or cutting knife, for guiding the movement of the same and holding it properly against "the upper surface of the "ledger plate during its operation.

The boss 13 has a shoulder 33 formed thereon, against which the lower forward corner of the cutter 'bar 1 engages.

In reducing the invention to practice, certain minor features of construction, combination, andarrangement of parts may necessitate alteration, to which the patentee is entitled, provided such alterations are'coinprehended within the scope of what is claimed.

What is claimed is V "1. In a cutter bar guard finger structure, a bottom section having a point formed upon one end provided with a cut-out portion extending downwardly therein from its upper surface rearwardly of said pointed end, a top section having a tongue formed therein, said tongue seated in said cut-out portion and pivotally connected to said bottom section, a shoulder formed upon the upper surface of said bottom section and extending transversely across the same, said shoulder being provided with a recess in its side wall facing said point, a ledger "plate having one end shaped to conform to and seated in said recess, a tongue formed upon the opposite end of said ledger plate remote from said first-named end, said tongue adapted for insertion into said first-named cutout portion and for engagement with the under surface of'the tongue formed upon said upper section for holding said ledger plate securely in place.

2. In a cutter bar guard finger structure, abottom section having a point formed upon one end provided with a cutout portion extending downwardly therein from its upper surface 'rearwardly of said pointed end, a top section having a tongue formed thereon, said tongue seated in said cutout portion and pivotally connected'to said bottom section, a shoulder formed upon the upper surface of said bottom section and extending transversely across the same, said shoulder being provided with a recess in its side wall facing said point, a ledger Gopies of this patent maybe obtained for plate having one end shaped to conform into said first-named cut-out portion and for engagement with the under surface ofthe tongue formed upon said upper section for holding said ledger plate securely in place, bosses formed upon the ends of said upper and lower sections remote from said pointed end, said bosses being provided with elongated substantially rectangularly shapedslots for'receiving'bolts for attaching said guard fingers toa'cutter bar'of ordinary construction.
